Leon Cooperman, founder of $10.7 billion hedge fund firm Omega Advisors, gave 12 stock recommendations at the Delivering Alpha conference Wednesday. Some were new, such as Actavis and Citigroup. Others were repeats of his previous recommendations made at the conference, such as SandRidge Energy and KKR & Co.

Cooperman broke the stock recommendations into four categories.

First was "growth at a reasonable price," where he picked Actavis, Citigroup and Thermo Fisher.
